Manu, Thanks for picking this up on twiiter. The question was somewhat inspired by not wanting to put both microdata and rdfa in a document. And it also occurred to me that the RDFa 1.1 profile mechanism could play role. If there is a profile, it similarly defines the processing of itemtype and itemprop. That's a small(?) extension of the model you describe. But I like the separate document for defining how to interpret microdata as RDFa. An '-i microdata' flag for RDFa parsers. All in the spirit of "just throwing it out there". -Sebastian On Tue, Sep 14, 2010 at 11:19 PM, Manu Sporny <msporny@digitalbazaar.com> wrote: > Here's an interesting idea from Sebastian Heath via Twitter: > >> sebastianheath: Has anybody thought about merging rdfa and microdata > > via @itemprop?
